Key Moments
- Calvert-Lewin watches a first-half header come back off the upright.
- Brenden Aaronson puts the hosts ahead with a low effort in the second period.
- Matheus Cunha equalises just three minutes later.
- The Yorkshire side extend their best Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles continued at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
The Everton loanee headed a first-period attempt against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward restored parity three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and slid a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, the boss has few attacking options.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical atmosphere, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
For a short moment, The home delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The job is not done yet but step by step, the team are getting nearer to achieving their survival.
Looking Ahead
